BASE FOR FURNITURE.

SPECIFICATION forming part of Letters Patent N 0. 533,155, dated January29, 1895. Application filed hiarch 19 1894. Serial No. 504,329. (Nomodel.)

To all whom it may concern.-

Be it known that I, LABS J. ANDERSON, a citizen of the United States,residing at Rockford, in the county of Winnebago and State of Illinois,have invented certain new and useful Improvements in Bases forFurniture, of which the following is a specification.

The object of this invention is to construct a base for furniture, inwhich the article of furniture is mounted upon a stationary base, andhaving a pivotal connection with a pivoted extension in order that itmay be turned about to bring the reverse face of the article offurniture to view.

In the accompanying drawings, Figure 1, is a plan view of myimprovements showing the parts in their closed position. Fig. 2, is aplan view showing the platform and pivotal extension at one quarter.Fig. 3, is an under face view of the platform. Fig. 4, is a plan view ofthe stationary base in which the piv- .oted extension is shown extendedin dotted lines. Fig. 5, is an isometrical.representation of the base inwhich the extension has been removed. Fig. 6, is an isometricalrepresenta tion of the under face of the pivoted extension.

The stationary base 1, is of rectangular form and has its upper faceprovided with a recess 2, of irregular shape and within this recess islocated a curved track 3, and a portion of the wall 4, of the recess isprovided with an undercut 5, and on the upper face of the recess islocated a roller 6, near the front face of the stationary base, and tothe rear face of the stationary base are secured perforated blocks 7,and a curved bar 8, is connected to the upper face of the stationarybase and overlies a portion of the recess.

An extension 9, is in outline form the same as the recessed portion ofthe base, and has a pivotal connection with the base by the pin 10,extending through the bar 11, which has a connection with the extension,its free end carrying a roller 12, which runs in the undercut 5, of thewall 4, of the recess.

To the under face of the extension is secured a roller 13, which runsupon the curved track 3, secured to the stationary base, and also has acurved flat track 14, secured to its under face and runs upon the roller6, secured to the base, this extension having a pivotal con nection withthe base, its inner end' guided by the roller 12, running in theundercut 5, and its outer end supported by the tracks 3 and 14, androllers 6, and 13. When this extension is in its closed position theouter surface of the stationary base will be filled in.

In the upper face of the extension is formed a perforation 15, and alsohas a circle of iron -l6, located around the pivot, and is laid in flushwith the upperface of the extension. The extension when in its closedposition will pass under the bar 8, extending across the recessedportion of the stationary base.

The platform 17, upon which is located the article of furniture is ofsuitable size to prop erly hold the article of furniture, its centerprovided with a stud 18, which enters the per foration 15, in the upperface of the extension, and in the under face of the platform are locatedfour rollers 19, which rest upon the circle 16, when the platform isplaced upon the extension, the pivot holding the rollers upon thecircle.

To the upper face of the stationary base and to the blocks 7 are pivotedlinks 20 and 21, and to the free end of each link is pivoted a bar 22,having an extension 23, which has a pivotal connection at its free endwith the under face of the platform 17, thereby forming a linkedconnection between the platform and stationary base.

When the pivoted extension is in its closed position within thestationary base, and the platform located thereupon and turned tooverlie the base, the platform may be turned face about by taking holdof the corner 24, and move it outward. The links 20 and 21, in theirconnection with the bar 22, will hold the pivot point of the arm 23,with the p1atform the required distance from the rear face of thestationary base in order that the platform may be turned about, andduring this movement of the platform its pivotal connection with thepivoted extension will cause the extension to move upon its pivot to theposition shown in dotted lines Fig. 4, and in solid lines Fig. 2, theextension forming a support for the platform as the center of theplatform in turning about moves beyond the face of Ioo he stationarybase, and the continued movement of the platform through its linkedconnection with the base and pivotal connection with the extension willcause the extension to retract to its closed position.

The bar 8, supports the linked connection between the platform andstationary base preventing the links from falling within the recessedportion of the base.

It will be noticed that a portion of the circle 16, extends under thebar 8, when the extension is in its closed position, but when thisposition of the extension has been reached the rollers 19, will restupon the circle in front of "the bar and as the extension moves on itspivot the circle will be brought clear of the bar in order that therollers may move uponits entire surface if necessary in turning theplatform about.

This construction of base is especially adapted for a combinationfolding bed.

I do not claim broadly a stationary base, an extensible section having apivotal connection with the base, and a platform supported by theextension and having a connection with the base; but

What I do claim as my invention, and desire to secure by Letters Patent,is-

1. A base for furniture consisting, of a stationary base, an extensiblesection having a pivotal connection with the base, a curved undercutportion of the base, a projection extending from the section supportinga roller upon its free end which is located Within the undercut.

2. A base for furniture consisting of a stationary base, an extensiblesection having a pivotal connection with the base, a platform supportedby the extension having a link con' nection with the base and a supportfor the link connection.

3. A base for furniture consisting of a stationary base having arecessed upper face, a curved track located in the recessed portion, aroller secured within the recessed portion and located near the front ofthe base, an extcnsible section located within the recessed portion andhaving a pivotal connection with the base, a curved track and rollersecured to the under face of the extension engaging the'curved track androller of the base a platform having a pivotal connection with theextension and a connection with the base.

4. A base for furniture consisting of a stationary base, an extensiblesection having a pivotal connection with the base, a platform supportedby the extension and having a linked connection with the base, throughthe medium of two like links pivotally connected with the base, and abar pivotally connected to the ends of the links and having a pivotalconnection with the platform.
